From the site:
Once cats & kittens enter our program they are never at risk of being put to sleep! We spay/neuter & fully vet ALL cats as they enter the program (rabies, FVRCP, micro-chip, de-worm, flea prevention is applied), we also provide any additional medical treatment where necessary (from drops for ear-mites, to in-depth medical procedures). They are then placed in foster care until we find their purrfect match!
If you'd like to give directly to our vet account please call West Houston Veterinary Medical Associates 281-493-3436, or you can write a check to "Dori's Darlings" and send c/o WHVMA, 13560 Briar Forest Dr, Houston, TX 77077
